Classes and Interfaces
DefCommandParser	Parses a DEF RUN command.
DefParseNode	Parse node that represents a DEF RUN command.

Class: DefCommandParser   next package

Parses a DEF RUN command.
Treat this class as "thread-hostile"; instances should be created, used and discarded by single thread at a time.

Constructors

public DefCommandParser()

Methods

public com.arsi.mj.maprpt.lexer.ptree.cmd.CommandParseResult parseCommand(com.arsi.mj.maprpt.lexer.tokens.IMaprptToken anInitialToken, com.arsi.mj.maprpt.lexer.MaprptLexer aLexer, org.springframework.context.ApplicationContext anAppCtx)     throws com.arsi.mj.MJTranslateException

Class: DefParseNode   previous package

Parse node that represents a DEF RUN command.
Treat this class as "thread-hostile" since it holds substantial state without method synchronization; instances should only be used by single thread at a time.

Fields

Constant that represents the LIN1 (next line) label. public static final int NEXT_LINE_LABEL = 2147483647

Constructors

Initializes an instance of this class. Parameters: aHostLine - Mapper report line that hosts this command. anOptionExpr - option expression parsed from DEF command, defaults to CLASSIFY_DEFAULT if command did not specify an option. anInfoVarExpr - variable reference as expression where info about variable-under-test is stored. aTestVarExpr - variable reference as expression that identifies variable-under-test. public DefParseNode(com.arsi.mj.maprpt.parser.line.types.AtLine aHostLine, com.arsi.mj.maprpt.lexer.ptree.expr.ICommandOptionExpr anOptionExpr, com.arsi.mj.maprpt.lexer.ptree.expr.ConcatExpr anInfoVarExpr, com.arsi.mj.maprpt.lexer.ptree.expr.ConcatExpr aTestVarExpr)

Initializes an instance of this class. Parameters: aHostLine - Mapper report line that hosts this command. anOptionExpr - option expression parsed from DEF command, defaults to CLASSIFY_DEFAULT if command did not specify an option. aLabelNumber - a label number (or NEXT_LINE_LABEL) to jump to if variable-under-test is not defined. anInfoVarExpr - variable reference as expression where info about variable-under-test is stored. aTestVarExpr - variable reference as expression that identifies variable-under-test. public DefParseNode(com.arsi.mj.maprpt.parser.line.types.AtLine aHostLine, com.arsi.mj.maprpt.lexer.ptree.expr.ICommandOptionExpr anOptionExpr, java.lang.Integer aLabelNumber, com.arsi.mj.maprpt.lexer.ptree.expr.ConcatExpr anInfoVarExpr, com.arsi.mj.maprpt.lexer.ptree.expr.ConcatExpr aTestVarExpr)

Initializes an instance of this class. Parameters: aHostLine - Mapper report line that hosts this command. anOptionExpr - option expression parsed from DEF command, defaults to CLASSIFY_DEFAULT if command did not specify an option. aLabelVariable - variable that contains label to jump to if variable-under-test is not defined. anInfoVarExpr - variable reference as expression where info about variable-under-test is stored. aTestVarExpr - variable reference as expression that identifies variable-under-test. public DefParseNode(com.arsi.mj.maprpt.parser.line.types.AtLine aHostLine, com.arsi.mj.maprpt.lexer.ptree.expr.ICommandOptionExpr anOptionExpr, com.arsi.mj.maprpt.lexer.ptree.expr.IVariableDerefExpr aLabelVariable, com.arsi.mj.maprpt.lexer.ptree.expr.ConcatExpr anInfoVarExpr, com.arsi.mj.maprpt.lexer.ptree.expr.ConcatExpr aTestVarExpr)

Methods

public java.util.List declareScalarVariables()

Get variable reference as expression where information about variable-under-test is stored. Returns: single variable dereference that identifies variable where information returned by DEF is stored. public final com.arsi.mj.maprpt.lexer.ptree.expr.ConcatExpr getInfoVariableExpr()

Get the literal label number to jump to if variable under test is not defined. Returns: label number, NEXT_LINE_LABEL, or NULL if label is variable reference or no label specified in DEF command. public final java.lang.Integer getLabelNumber()

Get variable that holds the label to jump to if variable under test is not defined. Returns: variable dereference that contains label, NULL if label is a literal or no label specified in DEF command. public final com.arsi.mj.maprpt.lexer.ptree.expr.IVariableDerefExpr getLabelVariable()

Get options applicable to command. Returns: options applicable to command (empty set if none). public final java.util.EnumSet getOptions()

Get variable reference as expression that identifies variable-under-test. Returns: typically a single variable dereference that identifies variable to test, but may be a literal (text) or reserved word. public final com.arsi.mj.maprpt.lexer.ptree.expr.ConcatExpr getTestVariableExpr()
